Atrometry (CANOPUS)

I'm wondering if anybody has used the astrometry software CANOPUS version 9.0.1.1?

I've been looking all over for some information on how to use the "auto astrometry" function. It was apparently well labelled in an older edition, but the new version doesn't clearly label what funtion performs auto-astrometry. I think I have found the function, but it would be really helpful to know what I need to set some of the parameters to, in order to detect the faint 19th V magnitude asteroids.

If anyone has ever used it and has come across a good tutorial or wouldn't mind explaining some things to me I'd greatly appreciate it. :)
